The cloud-edge-end collaborative offloading further addresses the problem of insufficient computing resources of edge servers owing to large-scale computing-intensive applications in MEC. However, existing offloading solutions often ignore the important factor of economic cost, making it hard for these solutions to achieve a sustainable cloud-edge-end collaborative computation. To this end, this paper considers a multi-user multi-server, cloud-edge-end collaborative offloading scenario in the presence of dependent offloading tasks for the sake of maximizing rewards and minimizing latency. Each user issues a computing-intensive application consisting of multiple dependent tasks, which are offloaded collaboratively by various computational resources. With the goal of maximizing the yield of offloading for users and server providers, a multi-objective optimization problem of joint task offloading and execution rewards is studied. Technically, a multivariate multi-objective optimization problem with three objectives is modeled. An efficient multi-objective evolutionary optimization algorithm based on MOEA/D is then developed to solve the latency minimization and reward maximization problems. Extensive simulation results verify the effectiveness of the algorithm and illustrate that the proposed algorithm can significantly improve user offloading benefits. In addition, a scalability evaluations of our proposed algorithm is conducted for demonstrating its feasibility in large-scale task offloading scenarios.& COPY; 2023 Elsevier B.V.

The standard 2-choice process corresponds to the case of G = K-n. For any k(n)-edge-connected, d(n)-regular graph on.. vertices, and any number of balls, we give an allocation strategy that, with high probability, ensures a gap of O( (d/k) log(4)n log log n), between the load of any two bins. In particular, this implies polylogarithmic bounds for natural graphs such as cycles and tori, for which the classical greedy allocation strategy is conjectured to have a polynomial gap between the bin loads. For every graph.., we also show an Omega( (d/k) + log n) lower bound on the gap achievable by any allocation strategy. This implies that our strategy achieves the optimal gap, up to polylogarithmic factors, for every graph... Our allocation algorithm is simple to implement and requires only O( log(n)) time per allocation. It can be viewed as a more global version of the greedy strategy that compares average load on certain fixed sets of vertices, rather than on individual vertices. A key idea is to relate the problem of designing a good allocation strategy to that of finding suitable multi-commodity flows.

Similarly, we also document the coexistence of generalist and specialist industries (based on their borrowing patterns). The observed interaction patterns in the credit market indicate a strong overlap in banks' loan portfolios, mainly due to specialist banks focusing their investments on the very same generalist industries.

Yet, little attention has been paid to investigating whether the sectoral international trade networks conform to a core-periphery structure, hence what is the role of different levels of processing in creating and maintaining structural inequality. This issue is of particular importance given the contemporary focus upon global production networks and reshaping of the international division of labor. With this in mind, we propose a model (LARDEG) from network science to reexamine old theories in economics, such as core-periphery structures in sectoral international trade networks and test whether the global value chains have changed structural positions in terms of the level of processing. The economic background of our model permitting a more accurate sorting of countries into structural positions and the general stability of results have provided for a more solid measurements than has hereto been possible. Our algorithm naturally produces networks with hierarchically nested block structure obtained from an iterative decomposition of the network periphery such that each block represents a vertex set of a maximal size subgraph existing at different levels. The results not only lend support to the previous hierarchical model of the world-system (core, semi-periphery, and periphery) but also find that, depending on particular industry, the number of analytically identifiable blocks could be more than three. We show that 'size effect' is the one that prevails for core block membership at the first hierarchical level, while the GNI per capita is a much poorer proxy for the world-system status. Moreover, the patterns of blocks we label as the second- or third-level 'core' are strongly dependent on distance and geographical proximity. Overall, the various configurations of asymmetrical trade patterns between our blocks and the remarkably stable position of core countries at the top of structure clearly indicate that the rise of global production networks has actually restored a huge and unequal international division of labor splitting the world into 'headquarter' and 'factory' economies.}, year = {2020}, eissn = {1932-6203} } @article{MTMT:31074681, title = {Firm size, quality bias and import demand}, url = {https://m2.mtmt.hu/api/publication/31074681}, author = {Blaum, Joaquin and Lelarge, Claire and Peters, Michael}, doi = {10.1016/j.jinteco.2019.04.004}, journal-iso = {J INT ECON}, journal = {JOURNAL OF INTERNATIONAL ECONOMICS}, volume = {120}, unique-id = {31074681}, issn = {0022-1996}, abstract = {Commonly used firm-based models of importing imply that firm productivity should have no effect on the allocation of expenditure across a common set of sourcing countries.

To rationalize this finding, we propose a novel model of importing that features (i) a complementarity between firm productivity and input quality and (ii) heterogeneity across countries in their ability to produce high quality inputs. This model implies that large firms bias their spending towards countries with a comparative advantage in producing high quality inputs and hence generates a non-homothetic import demand system.

We show that while lower interest rates and a currency depreciation associated with an expansionary monetary policy help to increase the value of exporting, the inflationary effects of the policy stimulus weaken the competitiveness of some firms, resulting in a contraction in firms' export participation. In contrast, positive productivity shocks lead to a currency depreciation and an expansion in export participation at the same time.

The proposed methodology allows to take into account a firm's choice of both exporting and non-exporting a product to a destination and to consider different forms of product complementarity that can generate product combinations. The empirical analysis uses a panel of transactions level data for the universe of Italian and French firms and complements the existing evidence along a few dimensions. First, we show that there is a high level of sparsity: selection of products at destination is indeed very severe. Second, we document that firms export several different combinations of product vectors across markets. Relatedly a high level of diversity is detected also when considering the intensive margin, pointing to a substantial departure from a stable global product hierarchy. Finally, we provide evidence that at the same time there exists a stable component in firms' product vectors across destinations composed by products which are not necessarily the most important in terms of sales, suggesting rich form of complementarities across goods.

Because administrative costs are incurred with every shipment, exporters have to decide how to break up total trade into individual shipments. Consumers value frequent shipments, because they enable them to consume close to their preferred dates. Hence per-shipment costs create a welfare loss.We derive a gravity equation in our model and show that administrative costs can be expressed as bilateral ad-valorem trade costs. We estimate the ad-valorem equivalent in Spanish shipment-level export data and find it to be large. A 50% reduction in per-shipment costs is equivalent to a 9 percentage point reduction in tariffs. Our model and estimates help explain why policy makers emphasize trade facilitation and why trade within customs unions is larger than trade within free trade areas. © 2015 The Authors.}, keywords = {Spain; EQUATION; EXPORT; Cost analysis; numerical model; Policy Making; shipping; welfare economics; trade flow; Trade facilitation; Gravity equation; Customs union; Administrative barriers}, year = {2015}, eissn = {1873-0353}, pages = {110-122}, orcid-numbers = {Hornok, Cecília/0000-0001-5680-3206} } @article{MTMT:2891795, title = {Per-shipment costs and the lumpiness of international trade}, url = {https://m2.mtmt.hu/api/publication/2891795}, author = {Hornok, Cecília and Koren, Miklós}, doi = {10.1162/REST_a_00468}, journal-iso = {REV ECON STAT}, journal = {REVIEW OF ECONOMICS AND STATISTICS}, volume = {97}, unique-id = {2891795}, issn = {0034-6535}, abstract = {Using detailed U.S. and Spanish export data, we document that trade costs of a per-shipment nature are associated with less frequent and larger shipments (i.e., more lumpiness) in international trade.
